This project is constructed based on careful theoretical analysis of materials of chance and reasons for the selection of the materials.
The theoretical analysis of heat principles and temperatures of the different fervid which in solid stage should set in the mould were analyzed.
The basic principles of cooling of the mould to avoid physical problems of cracks and distortions involved when high temperature are were studied. The cup mould design started with the choice of the optimal dimensions and then production of the wooden pattern.
With the completion of the wooden pattern of dimensions 26cm x 12cm x 5cm, the pattern was filled with chemical treated sand and fired over the oven for complete drying exercise. With the drying operation over, the patterns were filled with the sand and rammed well. The risers and provision for the core were all provided. The upper and lower parts of the pattern were tightly fixed together. The instance of the complete filling and ramming, molten aluminum from the furnace was poured into the pattern. After about one day, the pattern was opened and then the formed cup mould of aluminum produced. The cup mould was further cleaned and polished to give excellent production during use.
The cup mould was taken to Onitsha in a private plastic company, where it was test run and used to produce over low prolits type cups.
